Machine-sewn football

Abstract

The utility model discloses a machine-sewn football which comprises a ball bladder and a shell, the shell is formed by sewing a plurality of ball pieces, and a seam is formed between every two adjacent ball pieces. Ribs are arranged on the outer sides of the seams, and the ribs adhere to the outer sides of the seams to seal the seams. The ribs are attached to the seams of the football to seal the seams, so that the waterproofness and durability of the football can be improved; the end parts of the ribs are angles which protrude outwards, so that the ribs can be more tightly butted on the line seams, and the tightness is improved; and the ribs are very thin, so that the roundness of the ball is not influenced when the ribs are attached to the line seams, and the motion characteristics of the ball are not influenced.

Description

Technical Field

[0001] The utility model relates to the technical field of footballs, in particular to a machine-sewn football. Background Art

[0002] Machine-stitched footballs are a common type of football. Their outer shell is typically composed of multiple polygonal pieces (pentagons and hexagons are common). During the manufacturing process, these pieces are first arranged according to a specific design pattern, then machine-stitched along the edges to form a complete outer shell. The seams of these football shells are exposed on the surface of the ball, making it unsightly and prone to water absorption, which not only increases the ball's weight but also potentially affects its performance and lifespan. Exposed seams are also more susceptible to wear and tear from frequent kicking, reducing the ball's durability. Summary of the Invention

[0003] Purpose of the utility model: The technical problem to be solved by the utility model is to provide a machine-sewn football in response to the shortcomings of the existing technology.

[0004] Technical solution: A machine-sewn football includes a bladder and an outer shell. The outer shell is sewn from multiple pieces, and seams are formed between adjacent pieces. Ribs are provided on the outside of the seams, and the ribs are adhered to the outside of the seams to seal the seams.

[0005] Preferably, the rib thickness is 0.3-0.7 mm.

[0006] Preferably, the thickness of the rib is 0.5 mm.

[0007] Preferably, the width of the rib is 5-7 mm.

[0008] Preferably, the width of the rib is 6 mm.

[0009] Preferably, the ends of the ribs are outwardly protruding corners.

[0010] Preferably, the angle of the rib end is 90-120°.

[0011] Preferably, the angle of the rib end is 120°.

[0012] Preferably, the ribs are made of PU or TPU.

[0013] Beneficial effects: The utility model has the following beneficial effects:

[0014] The ribs are attached to the seams of the football to seal the seams, which can improve the waterproofness and durability of the football.

[0015] The ends of the ribs are angled outwards, which allows the ribs to be more tightly joined at the seams, thus improving tightness.

[0016] The ribs are very thin and sticking to the seams does not affect the roundness of the ball and will not affect the ball's movement characteristics. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] like Figure 1-3 As shown, a machine-stitched football of the present invention comprises at least a bladder and an outer shell 1. The outer shell 1 is formed by sewing a plurality of pieces 11, with seams 12 formed between adjacent pieces 11. Ribs 2 are provided on the outside of the seams 12, and the ribs 2 are adhered to the outside of the seams 12 to seal the seams 12.

[0022] The rib 2 has a thickness of 0.3-0.7 mm, preferably 0.5 mm, and a width of 5-7 mm, preferably 6 mm.

[0023] The ribs 2 will slightly protrude from the surface of the ball when pasted on the seams 12. After pasting, the ball can be placed in a heat setting device for heat setting so that the ribs 2 are almost flush with the surface of the ball.

[0024] The ends of the ribs 2 are outwardly protruding corners 21, with an angle of 90-120°, preferably 120°. When the angle of the corners 21 is 120°, the edges of the corners 21 of adjacent ribs 2 butt against each other to form a whole.

[0025] The ribs 2 are made of PU or TPU material.

[0026] The present invention uses ribs 2 attached to the seams 12, which can ensure that the seams 12 have better sealing properties, making the ball more waterproof and durable. The material of the ribs 2 allows them to be processed to be basically flush with the surface of the ball, without affecting the overall appearance and roundness of the ball, and without affecting the sports performance of the ball.
